Abstract
In a wireless microcell distribution system, a method is provided for embedding reference and control signals within the channel utilized for carrying the telephony signals, thereby eliminating roll off and cable tilt issues which are the result of providing the reference and control signals below the forward CATV band. The elimination of the signals below the forward CATV band also eliminates additional cable spectrum and installation difficulties which are the result of cable tilt in which frequency dependent amplitudes require compensation through the utilization of equalization for each cable microcell integrator.
